CARRIAGE-SHAFT COUPLING.

TO ALL WHOM IT MAY CONCERN:

Be it-known that I, T. H. WOOD, of Monroeville, in the county of Huron, and IState of Ohio, huve linventeflA certain new and useful improvements in Carriage-Shaft Couplings; and I do hereby declare-that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of' this specification, in which- Figure is a side view of the coupling. Figure 2, a. View of the top. Like lettersof reference refer to like parts in the dilferentviews.

A(fig.\1) is the clip by which the coupling is connectedto the axle-tree. From the side of this clip projectl a pair of lugs, B, (fig. 2,) between the cheeks of which is placed, on horizontal pivots C, the reaehD, to which the thills E are -attached. The reach referred to is made branching, as shown in iig. 2, in which figure it will be observed that the two branches are unequal in si-ze, D being the largest, and. consists of n. strong, thick piece of iron, whereas the branch D is very much thinner, and is made of steel, and serves as a spring, as will be hereafter shown. From thesides of the'pivots C projects a nih, E', (iig. 1,) which is` of a size that it will pass through the notch F cut in the side of the hole through which the pivots pass.

The manner of detaching the reach from the lugs is as follows: The thill or reach is turned (lown in thc direction indicated by the dotted line a, tig. 1. This will bring the nib in relation toA the notch so as to pass through it, which it will do on compressing the spring D' toward D, thereby drawing the pivots C from the holes. The reach, in consequence, is then free to be removed. l

By this arrangement it will be obvious that when the reach is in the position shown' in iig. l, the nibs will prevent the spring from being compressed 'toward the reach or branch of the rench D, and the tension of the spring will keep the twoiclose pressed against the inside of the lugs, thus making it tight and lsecure in its connection, and hence cannot be uncoupied without first bringing the thills flown, as oboveindieatcil, and then compressing the spring, in order to withdrew the pivots.

What I claim as my improvement, and desire to secure by Letters Patent, isl The spring D', section of the reach D, andpivots C, provided withnibs E, as arranged, in combination with the lugs B and clip A, for the purpose and in the manner set forth.
